There's this wrestler by the name of Steve Austin. I heard he did pretty well in the WWF.
Jericho, Guerrero, Benoit, Foley would qualify as well. Other than that WWE's had a lot of success with some former WCW jobbers like Taker, HHH, Edge, Kane. Just about everyone has worked for both companies at some point.
